WHEEL.

SPEGIFIOATION forming part of Letters Patent No. 473,728, dated April 26, 1892.

Application filed July 6, 1891- Serial No. 398,577. (No model.)

To aZZ whom it may concern:

Be it known that I, LOUIS .I. CRECELIUS, a citizen of the United States of America, re siding at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Wheels, of which the following is a specification.

My said invention relates to wheels adapted to be used for the transmission of power or to support portable machines or vehicles; and it relates to a form of wheel in which the hub is composed of a shell, in the cavities of which projecting ends of the spokes are embedded in fusible or plastic material contained and hardened in said cavities. Such a wheel is shown in my patent, No. 406,705, granted by the United States Patent Office on the 9th day of July, 1889.

My invention consists of a divided or seetional wheel of the kind above indicated and in which is a divided hub composed of parts containing cavities adapted to hold the material in which the spokes are embedded.

My said invention is shown in the accompanying drawings, in which Figure I represents in perspective the complete wheel. Fig. II shows the wheel composed of two parts, said parts being shown in perspective as separated from each other. Fig. III shows one-half of the hub in perspective with one end partially removed to show the ends of the spokes embedded in the filling. Figs. IV, V, and VI show sections of the hub. Fig. VII is a section of the rim of the wheel and of the coupling. Figs. VIII and IX show sections of the rim, also ends of the spokes fixed to the rim. Fig. X shows a perspective view of the wheel having three spokechambers in the hub. Fig. XI shows another form of rim-clamp especially adapted to a broad wheel. Fig. XII is a longitudinal section of the hub of Fig. X. Fig. XIII is a transverse section of the hub, showing the different forms of enlarged ends of the spokes embedded in the filling of the shells, these different forms of enlarged ends being adapted to be used in the same hub, as shown, or separately. Fig. XIV illustrates the method of filling the hubs.

In the drawings the Wheel is represented as divided into two parts, each part, as illus trated in Fig. II, being formed complete in itself and adapted to be bolted to its fellow to form a complete wheel. The half-hub (shown more clearly in Fig. III) is formed with cavities a, fitted to receive and hold the fusible or plastic material in which, when hardened, the ends of the spokes are embedded. The half of the hub shown in Fig. III has two of such cavities included in the shell Z) (which forms the peripheries of the hub about the cavity) and the partition-shell c, which is in the plane radial to the axis of the hub. These cavities or chambers are at the ends of the hub, as shown more clearly in Fig. V, which is a section in a plane at right angles with the plane of the divisional shells or walls 0, as shown in Figs. III and V. The chambers or cavities are closed at the ends of the hub and are open only to the interior, the interior opening being bounded by the walls, which have semicircular edges fitted to bear upon a cylindrical shaft or journal. The ends of the cavities of the section are closed by the walls 0, and the cavity is wholly closed when the section is placed upon a cylindrical shaft or journal.

A semi-cylindrical part of the shell 9 forms the middle part of the hub connecting the two chambered parts, and upon one side is a boss e, formed to receive a set-screw f, by which the hub may be fixed upon the shaft. The shell or wall I) at the periphery of the chambers is provided with holes 9, in which the spokes are inserted. The divisional plates are extended at the middle part thereof to form cars 71, in which are holes 1', adapted to receive the ordinary square bolts, by means of which the two parts are connected together, as shown clearly in Figs. I and VI.

The spokes are shown at k and the rim at Z. The sections of the rim are provided with clamps, by means of which they are held socurely together. These clamps are shown more clearly in Figs. I and VII, the latter figure showing more clearly the form which I prefer. The clamping part m has at its outer end a flange 0 and at the angle a recess 1), it thus being fitted to receive the bar n, which is formed with a tongue fitted to the recess 19. The general form of the clamp in cross-section is that of an ordinary angle-iron. These parts are each bolted at the abutting edge of its respective rim part, so that when the in-= wardly projecting parts of the clamp are brought together by the bolt the edges of the rim parts meet and areheld securely in place, the parts of the clamp being held to the rim parts by the rivets r. The outer ends of the spokes are held in the rim in the manner shown in Figs. VIII and IX. The end of the spoke may be reduced,as shown in Fig. VIII, or upset, as shown in Fig. IX, so as to fit the hole in the rim. It is made to project slightly through and to be upset, the hole being made flaring outward, as shown in the figure. One part of the hub is provided on the plane face of the divisional walls a with studs 6, which fit into corresponding holes in the opposing faces of the other part, and thus secure accurately the parts in place. The tongue upon the clamp-iron on the rim fitting in the recess 19 performs the same function for the rim. For wider rims the rim-clamps may be made in the form clearly shown in Fig. XI, in which there are three recesses and three tongues and an increased number of holes for securing the clamp to the rim.

In order to give more secure hold to the in-' ner ends of the spokes, I have formed them with enlarged inner ends. 7 This enlargement may be made by splitting the inner ends and turning the parts outwardly, as shown at the spoke 1 in Fig. XIII, or by putting a nut upon the threaded end ofthe spoke, as shown at 2, or by upsetting the spoke, as shown at 3, or by bending the end at right angles, as shown at 4.. As the spokes may be introduced from the inner side before the parts of the hub are fastened together, enlargements may be used upon the inner ends of the spokes with this I construction of hub.

My improved wheel is put together in the manner hereinafter described. The parts of the hub are first bolted together and then bored out to the desired size. Holes are punched or drilled in the periphery or outside shell fitted to the spokes. The hub is then taken apart and the spokes inserted and riveted to the rim, so that the two halves of the wheel are complete in themselves, lacking only to be put together and put into proper shape with the filling for the hollow hub. Then the parts with the clamps attached are put together by means above described and put upon a machine, which forces the rim into a circular form.

This machine is provided with a central mandrel, on which the hub is placed in perfectly true position. The mandrel is made hollow with lateral ports leading into the different spoke-chambers, as shown in Fig. XIV, where R is the mandrel and V are the holes leading from the bore S into the chambers a of the hub. The ends of the spokes having free play in the chambers will move in or out as the rim is rounded. WVhen the rim is fully compressed and shaped and while it is so held, the metal or other suitable material for filling the chambers is inserted through the hollow mandrel, (preferably under pressure,) and it surrounds and fixes the ends of the spokes in place and when hardened holds them securely. The wheel may be removed from the mandrel by turningit so as to break the connections between the hole V and the chambers. This leaves the bearing perfect, the chambers being in such shape as heretofore described. \Vhile the mandrel is in place the holes are perfectly closed, excepting the holes in the mandrel through which the material is forced. produced in exactly circular form. The construction is such that the wheel is light, strong, and cheap.

I have shown the wheel made in two parts, but do not limit myself as to the number of parts. The rim may be made of any suitable material, such as metal, Wood, or pulp.

I claim as my invention 1. A hub composed of parts, each part having a chamber opening toward the interior or axis of the hub, formed by the peripheral shell and end walls and having, also, divisional walls which lie in planes radial to the axis of the hub, the end walls having openings with the edges fitted to the shaft or journal, the inner edges of the divisional walls being also fitted to bear upon the said shaft or journal, the said hub parts being provided, also, with holes for spokes and being fitted to receive and combined with a fusible filling adapted to harden within the shell, substantially as described.

2. The method hereinbefore described of putting up a sectional wheel having chambered hub, the same consisting in inserting the spokes through peripheries in the chambers of the hubs and fastening the outer ends of the spokes to the rim-sections, then.

putting the sections together while the inner ends of the spokes are loose, forcing the Wheel by pressure upon the periphery into proper circular shape, and then forcing or pouring the filling material into the chambers about the inner ends of the spokes, all substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
